I'm in the process of planning a new 90-100 set up. I would love to go bigger however I am fighting with the boss on this and I also need to reinforce the floor prior to any set up. Considering that i am in the planning stages, the intent is to go with an fx5 or comparable eheim canister plus an AC110 or 2. I will be keeping Mbuna and would really appreciate the thoughts of the community on this matter. I really have considered a sump but the location of the tank may prevent that due to the potential for flooding, etc......so I keep coming back to the canister plus HOB. In addition, I am planning on UGJ, so again.....your thoughts are welcome....
